TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
Diagnostic Procedure Without CONSULT-IIINCS0002F
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-125, "Generic Scan Tool (GST) Function" .
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-62, "Malfunction Indicator Lamp (MIL)" .
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
When the ignition switch is turned ON, the indicator lamp lights up 2 seconds. As a method for locating the
suspect circuit, when the self-diagnostics start signal is input, the memory for the malfunction location is output
and A/T CHECK indicator lamp flashes to display the corresponding DTC.
Diagnostic Procedure
1. CHECK A/T CHECK INDICATOR LAMP
1. Start the engine with selector lever in “P” position. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> Go to AT- 1 7 2 , "
A/T Check Indicator Lamp Does Not Come On" .
2. JUDGMENT PROCEDURE
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Release accelerator pedal. (Set the closed throttle position signal ON.)
5. Depress brake pedal. (Stop lamp switch signal ON.)
6. Turn ignition switch ON. (Do not start engine.)
7. Wait 3 seconds.
8. Move the selector lever to the manual shift gate side. (Manual mode switch ON.)
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move the selector lever to “D” position. (Manual mode switch OFF.)
11. Depress brake pedal. (Stop lamp switch signal ON.)
12. Release brake pedal. (Stop lamp switch signal OFF.)
13. Depress accelerator pedal fully and release it.
>> GO TO 3.
3. CHECK SELF-DIAGNOSIS CODE
Check A/T CHECK indicator lamp. Refer to AT- 9 3 , "
Judgment Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 1 0 2 , "
DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 5 7 , "DTC P1815 MANUAL MODE SWITCH" , AT- 1 6 6 , "CLOSED THROTTLE POSITION AND
WIDE OPEN THROTTLE POSITION CIRCUIT" , AT- 1 6 7 , "BRAKE SIGNAL CIRCUIT" .
